.application filed. November 19, 1910.

To aZZ -zrfwm it muy concern.'

Be it known that l, Farm Baci *1v KLUGH, a citizen of the United States. residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in vMechanical Musical Instruments, of which the following is a full. clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this speciiication. l

.My invent-ion relates to mechanical musical intruments and especially to a type oit instrument commonly called a player piano. orl piano player.

The present invention relates more particularly. although not exclusively, to the accentuation of certain notes or series of notes to bring out solo eti'ects.

'I he object of the inventiomwwhen applied to piano players and player'pianos, isto provide means for producing the aforesaid solo eliects in an improved manner.

Certain broad features of the solo device herein set forth. are claimed in my copending application. Serial No. 551,14f0. tiled April S, 1910.

In the i'orm of carrying out .thc invention herein shown. l employ blow striking members, operated by power pneumatica. and removable means to limit the stroke of said blow striking .member-s. Broadly speaking. I also provide resilient means to change the strength of the blow.

l will describe my invention more in detail b v reference to the accompanying drawings, illustrating several forms ot' carrying out the invention. in which:

Figure 1 is a. side elevation. partly in section. setting forth the piano action. the operating pneumatics, the keys. and the music roll; Fig. 9 sets fort-l1 my improved music sheet as described in my aforesaid co-pending applica-tion; Fig. 3 is a front elevation` of a part of the mechanism shown in F ig.

1; and Figs. l and 5 show modifications-of the structure set forth in Fig. 1.

et'orring more particularly toFig. 1, l show a mechanical musical instrument having strings 1 to be struck bythe piano action. The latter involvesthe usual hammers 2 and actuating mechanisms therefor. The piano action is operated by pneumatics 5 governed by valve mechanisms 6. The valve mechanisms are connected by means Patented May 16, 1916.

or" tubes T to the tracker board 8 where a.

music sheet 9 in its well understood oper: tions selectively controls the actuation of the pneumatics Piano keys 10 may also operate the action as is well understood.

In accordance with my aforesaid copending application, l provide supplemental pneumatics 11. served by tubes l2 and leading to apertures 13 in the tracker board` for accentuating certain notes in order to produe what are called solo effects. The ordinary apertures 1l in the tracker board 8 are associated with the tubes 7. ln accordance with my aforesaid co-pending application, the music sheet has narrow openings or perforations 15 which, in the 'progress of the sheet over the tracker board, cooperate only with the apertures l-l, and wide openings or perforations 16 which cooperate with both apertures 1l and 13 of a given set.

lit will of course be understood that each set of adjacent apertures 13 and 14 serve the actions for the same note. `My supplemental pneumatics 11. through the medium of adjustable bars or rods417, control stops 18, which can be inserted or withdrawn from between the arms or levers 3 and an abutment- 19. lVhen a stop 1S is in place, as shown in Fig. 1. the movement of the corresponding arm or lever is limited lin that the downward pull of the respective pneumatic 5 can draw it only tightly against tire stop 1S, whereas. if'the supplemental pneumatic 11 controlling this stop is actuated to withdraw it toward the left. referring to Fig. 1, the arm 5 may move the entire length of its stroke when the 'pneumatic 5 is actuated. lt will be seen therefore that a supplemental solo pneumatic 11 serves when actuated to permit a louder tone of the particular note under consideration', because of the greater extent of movement of the respective power pneumatic in operating.

In Fig. '-l., l setforth special wedge shaped stops Q0 which in turn limit the strokes of the arms 3 and at the same time limit 'the strokes of the power pneumatics 5.

ln Fig. 5. l set Jforth avery important structure in that l employ resilient means, in this instance consisting of springs Q1 under the control of the supplemental pneumatics. It will be seen that, in the structure of Fig. 5, l interpose removableastops which may again be used to limit the 'strokes of the arms 3 or the power pneumatics 5, but which removable stops are resilient and afford yielding resistive effects when associated with the operating mechanism of an instrument of the class specilied.

The tracker board and music sheet disclosed herein are set forth and claimed in a copending application or'. mine, Serial No. 554;,142, tiled April 8, 1910, tracker board and music sheet.
